All basement models are completely wired and assembled at
the factory for ease of installation. The heat exchanger is de-
signed so that no restricting air baffles or shields are necessary.
Large capacity blower, mounted on rubber with a felt con-
nection at the outlet offers super quiet operation in addition
to the air requirements needed for air conditioning. All units
are fiberglas insulated and all controls are mounted inside the
full length vestibule for easy access. The smooth flowing lines
of the "round to square" heat exchanger is your assurance
of top operating efficiency.

Where Modernaire units are
to be installed with cooling
coils, larger motors to operate
against higher static pressures
are available. Capacity tables
at the left shows model sizes
and drives for use with units
equipped with cooling coils.
QUIET GAS BURNER
Single port is quiet, efficient and
provides trouble free operation year
after year. Flame retention ring
provides correct flame operation at
all times.
QUIET OIL
BURNER
Combustion chamber is
factory installed — rugged
refractory construction —
corbelled top design as-
sures quiet operation and
long years of service. Pres-
sure atomizing oil burner
is mounted and completely
wired at the factory. Oil
burner can be easily re-
moved by taking off three
nuts on the burner mount-
ing plate.
•
FIBERGLAS
INSULATION
Foil faced insulation
assures quiet operation
and minimum heat loss.
Solid steel base of the
cabinet is mounted on
full length steel chan-
nels which may be ad-
justed for leveling —
requires no grouting.
Cabinet is finished in
tough, baked enamel
silicone finish for long-
lasting durability.
HEAT
EXCHANGER
"Round to square" design of
the Modernaire heat ex-
changer permits smooth uni-
form air passages between the
heating surfaces. Tapered de-
sign means less resistance,
higher efficiencies and per-
mits smooth flow of air
through the unit.

SAFELY PACKAGED COMPLETE
IN ONE CARTON
The units, through
160,000 B.T.U. input, are
shipped in one carton
with the burner and all
of the controls com-
pletely assembled and
completely wired at the
factory.
The 200,000 input unit
is shipped in two car-
tons. The warm air
section has burner
installed and all controls
wired. The return air-
section has blower and
motor assembled with
two wires to be attached
to motor.
Well designed spacers hold the unit safely in the car-
ton for easy handling and shipping.
COMPACT ARRANGEMENT OF
COMPONENT PARTS
The heat exchanger and casing are designed so that
no air baffles or shields are necessary.
The large capacity blower, mounted on rubber and
with felt connection at outlet, is quiet in operation.
The large access door at the rear of the unit provides
ample space to change filters, oil or service blower
and motor.
HEATING AND
AIR CONDITIONING UNITS
QUIET GAS BURNER
The single port burner with flame
spreader is quiet, efficient and
trouble-free. The units are A.G.A.
approved for use with natural,
manufactured, mixed or L.P. gas.
Burner, pi-
lot, and safety
pilot are readily
accessible for
lighting or servicing.
They can be removed in one
piece after loosening the pilot gas
line, and the thermocouple lead.
FIBERGLASS
INSULATION
The foil faced fiber-
glass insulation as-
sures quiet operation
and a minimum heat
loss through the cas-
ing. The insulation is
held firmly in place by
full length metal bars
across the casing
panels.
The solid steel base
set up from the floor
on full length chan-
nels, provides a rigid
base which can be
levelled on the base-
ment floor and needs
no grouting.
The tough baked enamel applied to the casings as-
sures a bright, durable finish.
No detail has been overlooked to make the units
economical to install, accessible to service, and com-
fortable to live with.
ALL CONTROLS
ARE ENCLOSED
The burner, valves, regulator, manifold, blower and
limit switch and junction box are all mounted inside
the full length vestibule. All are easily accessible for
cleaning or service.
All controls, except the thermostat, are completely
assembled and completely wired at the factory. Only
the thermostat and draft diverter are mounted on
the job.
WELL DESIGNED* HEAT EXCHANGER
The smooth flowing lines of the round to square
design of the heat exchanger form the first step' in
the design.
The SQUARE radiator around the SQUARE body in
the SQUARE casing permits uniform air passages
through the unit between the heating surfaces. This
brings the air into close contact with all of the heating
surface. The tapered top and bottom surfaces of the
radiator present less resistance to the smooth flow of
air through the unit. There are no "circle in a square"
corners in the design.
*PATENTS PENDING
CUSTOM BUILT FOR EFFICIENT, TROUBLE FREE OPERATION
HEATING AND COOLING COMBINATION
Matching plenum and cooling coil can be installed
with the units to make a complete winter and sum-
mer combination heating and cooling unit. Standard
blowers have sufficient capacity for operating at the
higher static pressures encountered when cooling
coil is added. Only the motor and drive need be
changed.
It is practical to install the heating unit and the
matching plenum now and add cooling later.

stalled in place of the gas
burner at a reasonable cost.
HEATING & AIR CONDITIONING UNITS
Units are approved by the American Gas Association for
use with natural, mixed, manufactured or L.P. gas. They
are approved for both regular and high static pressure in-
stallations. Quiet, safe, trouble-free operation is assured.

return air cabinet have
very hard durable
baked enamel finish.
The Hi-Boy unit is ap-
proved for zero clear-

the narrow side air re-
turn cabinet, which
can be attached to
either side, it makes a
very flexible combina-
tion that will fit any in-
stallation requirement.

bottom panel is in place. Even when the unit is set
on an uneven floor, no grouting is necessary.
If return air is to be brought in on the other side of
the furnace, filter channels can be installed on the
opposite side. If return air is to be brought in through
bottom of unit, panel covering bottom opening can
be removed and filter channels installed in bottom
opening.
LARGE QUIET BLOWERS
The large capacity quiet blower provides adequate
air delivery for comfortable, carefree heating. Blow-
ers have capacity so that, with larger motors, they
will provide air enough for the addition of cooling.
Blower can be removed for cleaning or servicing by
removing one screw and sliding blower assembly
out on channels.
CUSTOM BUILT FOR EFFICIENT, TROUBLE FREE OPERATION
HEATING AND COOLING COMBINATION
Matching plenum and cooling coil can be installed
with the units to make a complete winter and sum-
mer combination heating and cooling unit. Standard
blowers have sufficient capacity for operating at the
higher static pressures encountered when cooling
coil is added. Only the motor and drive need be
changed.
It is practical to install the heating unit and the
matching plenum now and add cooling later.
BASEMENT
COUNTERFLOW
AND
HORIZONTAL UNITS
The units are also avail-
able in Basement,Counter-
flow and Horizontal Mod-
els to suit any installation.
OIL FIRED UNITS
It is possible to convert your
unit to burn oil without dis-
turbing unit or duct work.
An oil burner, firebox, and
primary control can be in-
stalled in place of the gas
burner at a reasonable cost.
HEATING & AIR CONDITIONING UNITS
Units are approved by
the American Gas Asso-
^s£^ ciation for use with
natural, mixed, manufactured or
Propane gas. They are approved
for both regular and high static
pressure installations. Quiet, safe,
trouble-free operation is assured.

sures a bright, durable finish.
No detail has been overlooked to make the units
economical to install, accessible to service, and com-
fortable to live with.
ALL CONTROLS
ARE ENCLOSED
The oil burner, primary control, blower & limit switch
and junction box are all mounted inside the full height
vestibule. All are easily accessible for cleaning or
service. The fire box is shipped in place within the
heat exchanger.
All controls, except the thermostat, are completely
assembled and completely wired at the factory. Only
the thermostat and barometric draft control are to be
mounted on the job.
WELL DESIGNED* HEAT EXCHANGER
The smooth flowing lines of the round to square
design of the heat exchanger form the first step in
the design.
The SQUARE radiator around the SQUARE body in
the SQUARE casing permits uniform air passages
through the unit between the heating surfaces. This
brings the air into close contact with all of the heating
surface. The tapered top and bottom surfaces of the
radiator present less resistance to the smooth flow of
air through the unit.There are no "circle in a square"
corners in the design.

HEATING AND COOLING COMBINATION
Matching plenum and cooling coil can be installed
with the units to make a complete winter and sum-
mer combination heating and cooling unit. Standard
blowers have sufficient capacity for operating at the
higher static pressures encountered when cooling
coil is added. Only the motor and drive need be
changed.
It is practical to install the heating unit and the
matching plenum now and add cooling later.

row side air return
cabinet, which can
be attached to either
side, it makes a very
flexible combination
that will fit any instal-
lation requirement.
The oil burner, primary
control, blower & limit

FITS ALL JOBS
Return air can be brought in on either side or through
the bottom of the unit. Filter and filter channels are
shipped installed on one side of the unit and the
bottom panel is in place. Even when the unit is set
on an uneven floor, no grouting is necessary.
If return air is to be brought in on the other side of
the furnace, filter channels can be installed on the
opposite side. If return air is to be brought in through
bottom of unit, panel covering bottom opening can
be removed and filter channels installed in bottom
opening.
LARGE QUIET BLOWERS
The large capacity quiet blower provides adequate
air delivery for comfortable, carefree heating. Blow-
ers have capacity so that, with larger motors, they
will provide air enough for the addition of cooling.

NTL OIL FIRED HORIZONTAL FURNACE
HEATING AND
AIR CONDITIONING
UNITS
Designed for Attic, Crawl Space, Basement or Commercial Installation
Compact design, quiet operation and efficient
performance make this horizontal oil furnace an
outstanding choice for any heating installation.
Air flow may be directed from left to right with
the flue outlet in the front or rear. The air flow
and flue outlet are reversed by simply invert-
ing the blower assembly. The "factory tight" heat
exchanger seal remains intact.
Oil burner and controls are packed separately in
one carton and are easily installed. The large blowers
have ample capacity for air conditioning applica-
tions. The design of the oil burner and the "square
to round" heat exchanger are two of this advanced
unit's features. Other features that mean depend-
ability and comfort are the ceramic firebox and the
fibreglass insulated casing.

SUMMER AIR CONDITIONING UNITS (Remote Condensing Units)
This modern dependable condensing unit when
coupled with a cooling (evaporator) coil can be
added to your present warm air heating system to
convert it to a complete "year round" air condi-
tioning system or it can be used as part of a new
installation to provide 12 months of comfort. Used
with an air handling unit it can
become a completely indepen-
dent summer air conditioning
system.
The attractive weather proof
cabinet is fabricated of zinc
coated steel phosphate treated
and given two coats of paint for
long life and to preserve its attractive appearance.
Many engineering features make this condensing
unit quieter and easier to service than other equip-
ment on the market. Condensed air is drawn through
the condensing coil minimizing noise and providing
most effective use of the entire coil surface. The
compressor and all electrical com-
ponents are enclosed in a sep-
arate sound proof, weather proof
compartment for quiet operation
and easy accessibility. All neces-
sary installation and service
checks can be made with the unit
running to eliminate guess work.

GENERAL
STEEL roof trusses are used largely for supporting
roof construction where a clear open floor space free
from interior columns or walls is desired. This construc-
tion is vital to gymnasiums, auditoriums, theatres and
airplane hangars. It is an essential feature in building
garages and certain types of industrial buildings.
Steel is particularly fitted for building roof trusses. It
is the strongest material for its weight known to the
building industry. The processes in its manufacture make
for consistent safety and security.
Two forms of roof trusses have proven of value to the
building industry — the curved chord or "bow string" and
the "A" type truss. The former type is a most econom-
ical form of truss in theory and practice. It results in a
lower building height with a minimum of material used
in the end walls of the building, a minimum of dead air
space to heat in winter and a minimum of roofing ma-
terial. In addition the curved chord truss is adaptable
for all types of roofing except overlapping decking de-
pendent upon the pitch of the roof such as slate and tile.
The "A" type truss is suitable with all types of decking.
Roof trusses can be and have been used for all spans
within the range of building requirements. They are par-
ticularly economical for spans up to 120 ft. Spans under
36 feet are usually framed to advantage with steel beams.
MACOMBER ROOF TRUSSES
Through the Macomber system of standardization
standard trusses are manufactured for all spans from 36
feet to 120 feet. Each truss is designed for a specific
maximum span. The end construction is reinforced and
designed for any span down to its minimum. In this
manner standard stock size trusses are available for the
complete range of economical roof spans.
As an example of Macomber standardization, the 38-CL-
truss is designed for a total load of 35,000 pounds for a 38
foot span. This truss will carry a total load of 37,000
pounds when used for its minimum span — 36 feet. The
total safe load for intermediate spans may be obtained by
interpolation. In the same manner the 40-CL truss takes
care of spans from 40 feet down to 38 feet. The CH
series of trusses duplicates the CL series for heavier roof
loads.
The trusses are designed in accordance with the Amer-
ican Institute of Steel Construction specifications. Safe
loading tables and overall dimensions are printed on the
following pages. As the Institute specifications have
been adopted almost universally for structural steel de-
signing the tables serve for all except a few cities. Safe
loads based on specifications other than Institute specifi-
cations will be furnished where required.
TRUSS DETAILS
All trusses are designed with conventional double angle
top and bottom chords. Angles and plates serve for the
web and end construction. Standard structural grade
steel, rolled from new billets, is used throughout. No
metal less than % inch in thickness is used.
All shop connections are fabricated with modern electric
arc welding. Solid beads of metal are added at the con-
nections that provide a factor of safety of five. Rigid
inspection insures connections that are stronger than the
members they unite.
The shorter trusses are shipped in one piece. The
longer trusses are shipped in two or three sections for
convenience in handling and erecting in the field. The
truss splices are designed for bolting with holes reamed
to 1/64" clearance and fitted with turned bolts. The trusses
are assembled and match marked in fabricating* to insure
speed and accuracy in assembling on the job.
The trusses are anchored to masonry pilasters with
standard wall anchors. The trusses rest on steel bearing
plates which may be bought locally and bricked into the
pilaster or these plates may be purchased welded to the
truss. The truss bottom chords are punched for bolting or
riveting to steel columns where supported on steel. A
standard extra charge is made for punching truss top
chords for attaching steel purlin construction other than
Macomber Bar Joists and Nailer Joists which are attached
with special connection bolts that do not require top chord
punching.
TRUSS BRACING
Bracing is recommended for all trusses to assist in lin-
ing them up and holding them in place during the erection
period. This is all that is required of the bracing in
buildings with shorter spans as the roof construction ef-
fectively braces the trusses after the building is com-
pleted. Buildings with longer truss spans should be pro-
vided with bracing that will transmit and transfer wind
stresses. Three types of standard bracing have been de-
signed to take care of practically all normal requirements.
Two of these— the "X" and "Z" types— are illustrated
on page 3. Special bracing is designed where standard
bracing does not fit the requirements of the building. This
particularly applies to buildings where line shafting or
machinery is suspended from the trusses.
ROOF TRUSS DESIGNING
The standardized form of Macomber Roof Trusses per-
mits an architect or engineer to lay out and design a build-
ing with these steel trusses as easily and accurately as with
simple beams. Any Macomber representative can pre-
pare definite recommendations and quote on the necessary
material except where heavier concentrated loads are to be
supported from the trusses. Only a slight delay is oc-
casioned where such special conditions must be referred
to our Engineering Department.
ADVANTAGES
The standardized features of Macomber Trusses speed
up every step from the preliminary layouts to the final
completion of projects involving roof trusses. Prompt
estimates and quotations are secured. Detailed checking
of the various truss members is eliminated as all trusses
are fabricated to standard shop drawings and based on
the same standard approved designs. Ample stocks are
maintained that permit fabrication immediately upon re-
ceipt of necessary punching details. Prompt shipment is
normally made after receipt of these approved details.
Standardized shop practice and engineering designs re-
sult in savings that make Macomber Roof Truss con-
struction decidedly economical where the advantages of
steel and sound engineering practice are desired.

Catalog No. 618.
Where trusses bear on masonry, wall anchors are provided. The ends
of the truss usually do not project into the face brick. Where this occurs
the trusses should be cut to allow 5 inches for face brick at each end.

ROOF DECKING AND PURLIN CONSTRUCTION
ON MACOMBER ROOF TRUSSES
The type of roof decking selected determines the type of purlins best
suited for carrying the decking and in turn determines the punching
required in the top chords of the trusses for attaching the purlins. Sec-
tions are shown alongside of and through the top chord of the truss to
illustrate different methods of attaching standard purlins.
CONCRETE OR STEEL DECKING
Where a 2" concrete slab is used for the decking, the concrete (or
satisfactory substitute) is poured on rib metal lath securely fastened to
the purlins. The maximum spacing of purlins should not exceed 30" to
secure a good decking. Either Macomber Bar Joists or Steel Channels
may be used for purlins. Bar Joists cost less than channels for the
average condition and provide a rapid and economical method of securing
the lath by driving wood lath wedges through the lath and between the
top bars of the joists.
Manufactured steel decking is secured to either Macomber Bar Joists
or Steel Channel Purlins with special clips furnished by the decking
manufacturer. The maximum spacing of purlins should not exceed the
carrying capacity of the decking and in no case should exceed 5 ft. in,
to secure a good job.
Figures 7 and 8 illustrate the usual methods of bolting Bar Joists to
the truss with Hook Bolts at each end of the joist. The exact spacing of
joists depends upon the designed roof load and should be left to the joist
manufacturer or determined from his published loading tables, Figure 1 1
illustrates the usual method of bolting channels to clip angles which in
turn are bolted to the trusses.
Concrete or manufactured steel deckings are used with good results on
Macomber "CL," "CH" and "A" Trusses. Corrugated iron sheets
provide the least expensive of incombustible deckings and are carried on
the same types of purlins. Steel straps are passed under the top bars of
bar joists or around the channels and riveted to the sheets. Care must be
used in lapping and riveting corrugated sheets to avoid leakage when used
on curved roofs,
WOOD DECKING
I" (%") plain sheathing, 2" OH") plain sheathing and 2" UH")
tongue and groove are common forms of wood deckings. All are nailed
to the supporting purlins. The maximum spacing of purlins should not
exceed the strength of decking used. The maximum spacing for good 2"
stock should not exceed 7 ft. 6 in. The maximum spacing for good 1"
stock should not exceed 4 ft. in. The sheathing should be ordered in
lengths to span three or more purlin spacing? and splices should be
broken. Plain sheathing should be spliced over the purlins. Matched
tongue and groove stock does not require splicing over purlins. Where
2" stock is used on curved roofs the purlins should not be spaced over
6 ft. apart at the maximum to insure a satisfactory roof.
Figure 12 illustrates the conventional decking nailed to wood purlins
which m turn are nailed to nailing strips bolted to the top chords of the
trusses. 2"x6", 2"x8" or 2"xl0" strips are used. These strips are bolted to
the trusses > in the field by the contractor. The length bolts required
varies and is specified on our erection plans. They are usually purchased
locally by the contractor.
Figure 11 illustrates steel channel purlin with wood nailing strip
bolted to the channe'. Channel purlins are not economical for close
purlin spacings and their use is largely confined to 2" decking. 13/16"
holes are punched in the top chord of the truss as required for attaching
the clip angles.
Figure 9 illustrates Macomber Roof Purlins Sections. The wood
nailing strip is secured to the steel top bars with screws and forms an
integral part of the purlin. Roof Purlin Sections are economical for
spacings from 4 ft. to 7 ft. 6 in. and are largely used with 2" decking.
The exact spacing should be left to the purlin manufacturer or determined
from his published loading tables. Two 11/16" holes are punched in each
top chord angle as required for attaching purlin ends with W bolts.
Figure 10 illustrates Macomber Nailer Joists used as purlins. The
nailing strip feature is identical with that of the Roof Purlin Sections.
The joists are economical for purlin spacings of from 18" to 48" and are
used largely with 1" decking. The exact spacing of joists should be left
to the joist manufacturer or determined from his published loading tahles.
The joists are attached to the truss top chord with special bolts as illus-
trated.

SAFE LOADS: Trusses are designed in accordance with the
American Institute of Steel Construction Specifications. All loads
listed are TOTAL SAFE LOADS uniformly distributed expressed
to the nearest hundred pounds with trusses braced laterally as in
standard roof construction.
TRUSS HEIGHT: Overall height of all CL and CH trusses is
approximately l/10th the maximum span; of 40-A to 60-A trusses is
approximately l/4th the maximum span; of 64-A to 84-A trusses is
approximately l/5th the maximum span.
LIVE LOADS: Building Codes usually govern the live load
requirements. In absence of building code information the following
live loads represent usual practice.
States south of Mason-Dixon Line 25 Ibs./sq. ft.
Extreme northern states having excessive snowfall 40 lbs./sq. ft.
The rest of the United States 30 lbs./sq. ft.
—TOTAL LOAD : To the roof live load add the dead load of decking
and purlins (see page four). Where metal lath and plaster ceiling is to
be carried by the trusses add 10 lb./sq. ft. All quotations and estimates
furnished by Macomber Representatives are based on and include the
dead weight of trusses and bracing required. This ranges from 2 to 7
lbs./sq. ft. depending on the span and spacing of trusses and can be
taken at 4 lbs./sq. ft. for average conditions. Concentrated loads iuch
as suspended balconies or monorail systems should be clearly specified in
asking for quotations.
STANDARD SPECIFICATIONS
THE following specifications are for the pur-
pose of aiding architects and engineers in
specifying steel Roof Trusses of the Macomber
type and to assist Building Commissioners in
drafting building code sections.
GENERAL
All trusses shown in the plans shall be Macomber
Steel Roof Trusses as manufactured by the Ma-
comber Steel Company of Canton, Ohio, The
trusses shall be designed to carry the dead weight
of the roof construction as shown on the plans and
a live roof load of pounds per square
foot. (Where required) In addition the trusses
are to carry concentrated loads as shown on the
plans and specified as follows:
Full facilities are to be provided by the manu-
facturer at all times for the proper inspection,
chemical or physical, of the materials used and
the workmanship employed in the manufacture.
DESIGN
The trusses are to be designed
with the specifications of the Ame
of Steel Construction. Structural
form to the standard specifications
can Society of Testing Materials
Steel for Buildings shall be used
members. No metal less than l /±"
to be used.
SHOP CONNECTIONS
All shop connections shall be fabricated with
electric arc welding and shall be designed for a
factor of safety of five. Each weld shall be indi-
vidually inspected and tested in accordance with
the manufacturer's standard practice.

for Structural
for all truss

FIELD CONNECTIONS
Where trusses are built in sections and assem-
bled in the field, all field connections are to be de-
signed for bolting. Truss sections shall be assem-
bled and match marked before shipment. Turned
bolts are to be provided for truss splices and holes
reamed to 1/64" clearance.
BRACING
All trusses are to be adequately braced with
standard Macomber bracing as recommended for
the spans and roof construction specified.
BEARING
(Steel Columns) Trusses shall be connected to
steel columns as shown in the plans. The truss
ends shall be punched as specified for column con-
nections. Connection bolts shall not be considered
as part of the truss contract but shall be furnished
with the columns.
(Masonry) Trusses shall rest on and be bricked
into masonry pilasters as shown in the plans.
Standard Macomber wall anchors shall be provided
for anchoring trusses to the masonry. The trusses
shall rest on steel bearing plates either loose or
welded to the trusses. The bearing pressure under
the plates shall not exceed-—. -pounds per
sq. in.
PAINTING
All trusses and bracing shall be given one coat
of standard shop paint at the factory before ship-
ment.
DETAILS REQUIRED IN ORDERING
It is recommended that quotations be asked for
and orders placed for trusses and truss bracing on
a lump sum basis freight allowed to nearest rail-
way siding. Full plans for the project should be
submitted to the Macomber representative or our
home office at Canton in asking for quotation. It
is frequently to the purchaser's advantage to com-
bine and place orders for purlins, steel windows,
columns, etc., with the truss order. This centers
the responsibility for the steel requirements and
results in savings in handling the combined order.
The following information is necessary to quote
intelligently on trusses and bracing;
1. TOTAL LOAD: This includes the roof live load,
the dead load of roof construction, the dead load of
ceiling construction and the amount and location of
concentrated loads. Each should be clearly specified.
Our engineers are available to make definite recom-
mendations as to live and dead loads where our ex-
perience can be utilized to advantage.
2. SPAN: The clear span between supporting col-
umns or pilasters is required.
3. LIMITATION IN SPACING OF TRUSSES:
Where possible the center to center spacing of trusses
should be left to the Macomber representative or en-
gineer to utilize the full carrying capacity of the trusses
best suited for the requirement. The exact spacing of
trusses should be stated where the building design
determines the spacing.
The following information is essential to enter
and ship truss orders:
1. Truss symbol and number of trusses.
2. Overall length of truss.
3. Center to center spacing of trusses and (where
bracing is to be furnished) type of truss bracing.
4. Punching in top chord for attaching purlin con-
struction, except where Macomber is to furnish the
purlins.
5. (Masonry pilasters) Maximum permissible bear-
ing pressure.
5-a. (Steel columns) Details for punching trusses for
connecting to columns.
6. Such other punching details as may. be required
for attaching suspended balconies, hoists, monorail
systems, column knee bracing, etc.
